人工诱导番茄四倍体,当作遗传传递的工具,有重要的育种用途。籍助染色体重组工程,诱导番茄多倍化,实现基因转移,不仅可获得座果多而品质好的番茄新品系。还可克服远缘杂交中的不亲和性、杂种不孕性等,从而培育新品种。试验结果表明:用中等剂量的秋水仙素处理减数分裂前的细胞,并结合涂抹幼苗生长点的方法,产生番茄四倍体的频率大,植株茎部粗壮,叶色深而宽厚,座果多而果实大。但需加强田间管理,才可在生产中应用。 Artificial induction of tetraploid tomato, as a tool for genetic transmission, there is an important breeding use. With the help of chromosome recombination project, inducing polyploidization of tomato and gene transfer, not only the new tomato line with more fruit but better quality can be obtained. Also overcome the incompatibility in distant hybridization, hybrid infertility, etc., so as to cultivate new varieties. The results showed that: with a moderate dose of colchicine treatment of meiotic cells, combined with the method of smearing the growth point of the seedlings, resulting in tomato tetraploid frequency, plant stem stout, deep and generous leaf color, fruit More and more fruit. However, it is necessary to strengthen field management before it can be applied in production.
